Product Description

The half thread hex bolt M20x180 is a hexagonal half thread bolt designed for heavy-duty industrial fastening applications. This M20x180 external hex bolt features a 20mm nominal diameter, 180mm total length, and partial threading covering approximately 50% of the shank length. Constructed from grade 8.8 carbon steel with zinc plating, it offers a tensile strength of 800 MPa and operates in temperatures from -30°C to +150°C. The standard hexagonal head accepts 30mm wrenches and complies with ISO 4014 specifications. Widely used in structural engineering, machinery assembly, and bridge construction, this bolt combines shear resistance from the unthreaded section with adjustable tensioning via the threaded portion. Key advantages include corrosion resistance and vibration tolerance, though precise torque control during installation is critical. The partial thread design minimizes stress concentration while maintaining clamping force integrity in dynamic load environments.
